- any devices and devices can be coupled to a valve terminal and communicate with this, which is not possible in known from the prior art valve islands in this form.
- the data signal can z. B. may be a parallel electrical data signal with which individual consumers can be controlled. In this case, a conversion takes place directly into a serial optical signal. In an advantageous embodiment, it is a bus signal, which is first converted in the coupling module into a parallel electrical and then into a serial optical signal.
- the coupling module can be adapted very advantageous to a variety of waveforms.
- the electrical data lines preferably form a bus system. In this case, the coupling module forms the last module of a bus node. In particular, the bus system may be a local bus system.

- the valve station 200 may be connected to the field bus node 100, for example via a rail 300.
- the coupling module 120 is adapted to the bus system, for example a local bus, whereas the transmitter / receiver module 220 is adapted to the valve modules 210 with regard to its optical data transmission behavior.
- Fig. 1 shows the coupling device for better explanation of the optical transmission path in the unfinished state.
- the optoelectronic transmitter / receiver module 122 of the coupling module 120 is located directly opposite the optoelectronic transmitter / receiver module 222 of the transmitter / receiver module, the entire arrangement being supported by the rail 300, which is not visible.
